// srouce code

BEGIN_MESSAGE_MAP(Cmfc1Dlg, CDialogEx)
    ON_MESSAGE(WM_MY_MSG, &Cmfc1Dlg::OnMyMsg)
END_MESSAGE_MAP()


LRESULT Cmfc1Dlg::OnMyMsg(WPARAM wParam, LPARAM lParam)
{
    TRACE("get msg %d/n", (int)wParam);

    //block all the upcomming messages in the message queue
    while(1);

    return 0;
}

void Cmfc1Dlg::OnBnClickedButton1()
{
    for(int i = 1; i <= 100000; i++)
    {
        if(!PostMessage(WM_MY_MSG, (WPARAM)i, 0))
        {
            TRACE("post fail i = %d, last error = %d/n", i, GetLastError());
            break;
        }
    }
}
